Someone should read how to disagree (http://www.paulgraham.com/disagree.html http://www.paulgraham.com/disagree.html). He is criticizing something that Sal probably got wrong. Sal could probably do a better job of using findings in educational research to make his videos and exercises better. But the author seems to be implying that KhanAcademy as a whole is of poor quality. I think he's using a DH5 to argue something that requires a DH6.
I think Sal does an excellent job with his videos as a whole. He does a good job of explaining things in an intuitive and deep way. See http://www.collegeanswerz.com/rethinking-education http://www.collegeanswerz.com/rethinking-education for more information. Or read Sal's book http://www.amazon.com/The-One-World-Schoolhouse-Reimagined/dp/1455508381 http://www.amazon.com/The-One-World-Schoolhouse-Reimagined/d....
- snori74 13y agoThanks for that link to "how to disagree" - one I hadn't read.
- adamzerner 13y agoYeah, no problem! It's one of my favorites.
- gpcz 13y agoAs Khan Academy makes lessons for younger students, I believe the argumentation will get more passionate like this article. Students increasingly learn to teach themselves as they get older, so I believe the media will let Khan "get away" with more perceived "flaws" in his Algebra and Calculus lessons than on something for younger children.
- padolsey 13y agoOP seems to be hovering around DH5/DH6. I don't see the problem.
- adamzerner 13y agoHe's (at least) implicitly saying that KhanAcademy sucks. I didn't really read it too too carefully, but that's the sense I get from it. He seems to be pissed about an error that Sal made, and is jumping to conclusions saying that KhanAcademy sucks. To make that claim, you'd have say what it means to suck, and why KhanAcademy does so (DH6).
- bayesianhorse 13y agoI think the criticism would be valid as long as Khan's videos were damaging education... but they are improving people's understanding of math. Khanacademy is being optimized for effective learning. But that takes effort, and it might never be perfect.
- makomk 13y agoOf course, the entire point of the blog is that they're actually cementing people's existing misunderstandings of math...
